Polycrystalline film growth during coevaporation in real time using in situ X-ray diffraction and fluorescence analysis. Credit: R. Mainz, C.Kaufmann/HZB. Photovoltaic cells based on thin films of copper indium gallium selenide are among the most promising and efficient PV technologies, and coevaporation is a common technique used for CIGS cell fabrication. The process involves simultaneous…
